Data migration method and device, computer equipment and storage medium

The invention relates to a data migration method and device, computer equipment, a storage medium and a computer program product. The method comprises the steps of obtaining a to-be-migrated cold data set based on a data migration request; performing cloud data identification conversion on the data identification in the cold data set to obtain a target cold data set; performing object data conversion based on the target cold data set to obtain a cloud object data file, and determining target metadata and target index information corresponding to the cloud object data file; storing the target metadata and the target index information in an associated manner, wherein the target metadata and the target index information are used for accessing a cloud object data file in a cloud object data storage space; and performing data migration on the cloud object data file, the target metadata and the target index information to the cloud object data storage space, and deleting the cold data set when data migration is com
